This invention pertains to metal windows, and more particularly towindows such as casernent windows, which open or close on a hinge orpivot.

One of the objects of this invention is to provide a window 0f this typewith a weatherstrip which will effectively seal the same against theweather.

Another object is to provide a weatherstrip which will make yieldingengagement with the window in such a manner as to provide aweather-tight seal.

Another object is to provide a weatherstrip for such a window of novelform and simple construction.

Another object is to provide novel means for mounting such aweatherstrip in place.

Another object is to provide such a. weatherstrip and mounting meanswhich will be cheap to construct, simple to install, and effective anddurable in service.

Further objects will appear from the following description, taken inconnection with the accompanying drawing, in which- Figure 1 is afragmentary sectional view of a. window embodying this invention;

Figures 2 and 3 are similar views, showing other embodiments of thisinvention; and

Figure l is a perspective detail showing the method of securing theweatherstrip in place.-

Referring to the drawing, 1 designates the wall of the building and 2 isthe window frame, which may be of wood or other suitable material withwhich the window opening is lined. A metal window frame 3 is arranged toline the opening of the frame 2. The frame 3 may be constructed ofrolled steel or similar material and may have generally a Z section, asshown in Figure 1, although other angular sections may also be used. Theframe may be mounted in place, as illustrated, with one flange 4c of theZ forming the outer face of the window frame, shown at the top inFigure 1. A web 5 eX- tends toward the inside of the building, while aninnerflange 6 forms the inside face of the window frame.

The window sash may be constructed of rolled steel of similar section,having an outer J face 7 a web 8 and an inner face 9. The glass 1928.Serial No. 287,659.

10 may be mounted in the sash against the flange 9 and held in place byputty 11 or other suitable fastening. The sash swings on a pivot orhinge (not shown) moving outwardly, in the case shown in the drawing,from the position illustrated, when the window is opened. Upon openingor closing the window, therefore, the flanges 7 and 9 come into abuttingengagement with the corresponding iianges of the frame 3.

A weatherstrip 12 is provided in the form of a strip of flexiblematerial, such as thin metal folded lengthwise, so as to have generallya U-shaped cross-section. One leg of the U may be made straight, asillustrated in the drawing, while the other leg is curved and extendsoutwardly to a position to be engaged by the edge of the sash as willpresently be more fully explained.

The strip 12 is held in place by a clip 13, which'is generallyrectangular in form and has an obtuse bend lengthwise of its middleportion. Near the middle of the clip 13, a lug 14 is cut from thematerial thereof, bent up wardly, and provided with an internal threadadapted to receive a tensioning screw 15. The screw 15 is passed througha hole drilled in one of the faces, as, for instance, the face 6 of theangular frame 3, and `engages the clip inside the angle. Theweatherstrip 12 is inserted with its straight side between one end ofthe clip 13 and the web 5 so as to lie against said web. One end of theclip 13 then engages the inside of said strip, while the other end restsupon the inside face of the flange 6 at a point beyond where the screw15 passes through said flange. It will be seen, therefore, that in thisarrangement one end or abutment of the clip 13 engages the weatherstrip12, while the other end rests on 9 the other face of the angle, and thescrew 15 provides a tensioning member adapted to apply tensioning forcebetween the ends of the clip. This has the efl'ect of forcing the clipfirmly against both faces of the angle and, therefore, to press thestrip l2 firmly into engagement with the web so as to secure the. samerigidly in place.

One part of the strip 12 is, therefore, held firmly against the frame 3,while the other 'm edge extends outwardly to a point close to the flange6. This outer edge is in a position to be engaged by the edge of thesash when the latter is closed. This engagement takes place by a slidingmovement, which presses the strip 12 inwardly against its resiliency sothat, when the window is closed, the weatherstrip bears against the edgethereof with a firm yielding pressure all along that edge. This providesa tight joint through which it is practically impossible for air to beforced.

It is clear, of course, that the strip 12 may be mounted upon the sashinstead of upon the frame 3. This construction is illustrated in Figure2. Since both the sash and the frame have the same cross-section, theengagement of the weatherstrip will be the same in both cases.

In the embodiment of Figure 8, weatherstrips are placed upon both theframe and the sash. In this case, they will either engage each other, asshown in Figure 3, or each will engage the edge of the other member incases where the lip 16 is long enough.

It will be seen, therefore, that this invention provides a windowconstruction which is not only extremely simple to install and cheap tomanufacture, but which makes a very effective weather seal. Theoutwardly extending edge of the strip 12 lies close to the flange 6 sothat, when the window is open, there is no sharp edge of the strip 12exposed, and it is practically impossible to come into accidentalcontact with this edge. Vhen the window is closed, the strip is pressedwith a yielding pressure against the sash. This pressure is at rightangles to the movement of the window and, accordingly, the strip is insuch a position that the bending incident to such engagement is not suchas to cause a permanent set in the strip 12.

The clip 13 provides an ideal fastening for such a strip, as it may bemounted on the frame before the strip l2 is put in place. The screw 15is made long enough to permit tipping up the outer end of the clip sothat the strip may be inserted therebeneath. The head of the screw 15 ison the inside face of the frame where it is easily accessible foroperation to tighten the clip. The clip 13 rests at its lower end on theflange 6, while the screw 15 applies its force between the ends of theclip so as to force the other end firmly against the strip 12.

With the window frame and sash construc tion as illustrated in thedrawing, in which the two angle sections abut each other with the anglesfacing one another, a space is provided within the angles, and thesealing strip, being mounted within this space, is hidden from View andprotected against injury.

uThe fastening clips 13, being mounted within the fold of the strip, arealso hidden from view, so that all exposed parts present a smooth andorderly appearance.

It is obvious that various changes may be made, within the scope of theappended claims, in the details of construction without departing fromthe spirit of this invention. It is, therefore, to be understood thatthis invention is not to be limited to the specific details shown and/ordescribed.
